Skeptics immediately read the MJ-12 papers as disinformation and forgery

Evidence

MJ-12 immediately polarized the UFO community into believers and skeptics. Among the skeptics was Jacques Vallee, who compared the incident to the activities of “Deep Throat” during the Watergate scandal. He suggested that the documents’ sender was more likely interested in disinformation than in whistle-blowing, and implied that the documents were forged. Even more dismissive was Philip J. Klass, a longtime debunker of UFO hoaxes, who argued that the format and language of the documents pointed to forgery. — Michael Barkun, A Culture of Conspiracy, 442
